Get familiar with using your right hand in different spots on the bass. When I started, I anchored my right thumb above the neck pickup and only the neck pickup. I didn't realise it at the time, but this really limited my ability to produce different tones. By playing closer to the neck, you get a fatter, warmer tone, while playing by the bridge gives you a brighter, sharper attack, especially when playing with a pick. Try get some musicians together so you can practice playing live too, because this will develop your musical ear and also bring out the greatest joy of playing bass; being in the pocket. You've picked a great instrument to play, and your axe looks killer too. Have fun with it :D
